Hi!

Sorry for the late answer, I did not checked the BTCTalk soon few weeks

Its was several bug in the javascript in the last time, but for now should work as expected.

ETH Price was even higher

Hi IFA,

Does your lottery still work? I have a problem with loading the coinhive script on a computer from which I even removed the antivirus program. Can you relate to this issue however?

... or maybe the eth price is too high? 

The Faucet contest has ended. Congratulations for the winners!

Attention!

We start a Contest on the website's https://ethereumlottery.net Faucet with two reward.
The Contest duration is from 2016-08-15 00:00:00 to 2016-09-15 23:59:59. (Year-Month-Day Hour:Minute:Second)
#1 Goal: Claim the most in the Contest duration to win the prize. Prize: 5 ether
#2 Goal: Referral the most people in the Contest duration to win the prize. Your referral is only valid after one her/his claim. Prize: 5 ether

Attention!

Investors are needed to my Weekly Lottery B type game. The game is a verified contract on the Ethereum blockchain: https://etherscan.io/address/0x3e368966c54C606ef545cCafD43af8bE1deF734F#code

This game is a regular lottery, where 3 numbers out of 50 should be chosen. Winners are tickets with 2 or 3 hits.  One ticket costs 0.1 ether. The tickets can be bought every week until Saturday 12:00:00 (UTC). After that comes the Drawing of lots. Chances for winning:
3 hit: 1:19600,
2 hit: 1:139.

One investment unit is 1 Ether. The investment must be at least 10 units. Canceling the investment is only possible only after 5 draws, and only 24 after hours after the 5th draw. 40 % of the price of each ticket goes to the Investors, in proportion of the invested sum, to a separate balance. This separate balance is called the Profit Balance, and can be withdrawn at any time by its owner.
The sum of the investment amounts and an amount coming from the ticket prices makes the Jackpot. When someone hits the Jackpot, then the state of each Investor will become inactive. An inactive Investor would not continue to receive its share from the Tickets and can’t withdraw his/her funds, only the Profit Balance.

The investment can be done at any time with help of the Đapp.

Calculation of Expected profit:

A = Rate of full hit
B = Ticket price
C = Percent of the ticket price going to Jackpot
X = Our investment amount
Y = Investment amount of the others
Z = Expected profit

Z = ( ( A * B * ( C / 100 ) ) / ( X + Y ) * X ) - X

Example:
( ( 19600 * 0.1 * ( 40 / 100 ) ) / ( 200 + 400 ) * 200 ) - 200 = 61.33 ether

When the contract becomes inactive, then the players and Investors have a 5 week window to withdraw their winnings or funds from the contract.
More technical details can be found here: https://ethereumlottery.net/doc/WeeklyLotteryB.html

For big investors with more than 1000 Ether, the contract can be modified, and a new contract can be created, where instead 3 numbers, 4 numbers must be chosen. Then the winning rate in this case is:
4 hit: 1:230300
3 hit: 1:1251

Then the likely profit is:
( 230300 * 0.1 * ( 40 / 100 ) ) / ( 200 + 400 ) * 200 ) - 200 = 2870.66 ether

Ok thank you very much for your answers, i hope next time  your services more support for android (today is era of smartphone) and add FAQ soon. It will easy for use your services.

Ok thanks fo the reply, I'll be looking into it

Long depending on players. I can't say how much ppl would play with the game in the future.
But if you don't want anymore invest, you can cancel it after 1 day from your invest begin.

Current contract address is: 0xe3014aaF39CE3A2de10B8CCfcCF8118880c3eca2
I have troubles on etherscan.io and i cannot verity my contract.

On ether.camp is all fine:
https://live.ether.camp/account/e3014aaF39CE3A2de10B8CCfcCF8118880c3eca2

This is the 2.2.0 version of the contract.

30% is a nice ROI ! How long should it take to get such a ROI ?

Is this the right address ? https://etherscan.io/address/0xe3014aaF39CE3A2de10B8CCfcCF8118880c3eca2

Dear Disruptor,

The contract is modified today. Please read careful the documents: https://ethereumlottery.net/doc/dEthereumlotteryNet.html

ROI depending on players bet amount. Calculated interest is +30% of the investment.

Hi I'm interested in investing in a gambling game.
What is the potential ROI for your dlottery ?

News!

https://ethereumlottery.net/?type=d

Play/Invest/Check contract

what do you mean ?

Maybe I'll invest the ether you sent me in your game

Thanks, i count on you later

Thanks IFa

Good luck with your project 

Yes it's my address, it's a new account (trying Jaxx on Ios  ).

Please confirm your addres, because this account has no one ether on it.

Hey IFa,

Ok good to know it was only a typo.
Thanks for the generosity to thanks me

0x002a6f2dDb6Ed62067Bda1B813493aE4BB3574e8

Dear sydhelly,
Thanks for you check, this was a typo. One ! Missing before the function. I have fixed it, but I deploy the contact only tomorrow. I have modified today few little things, because I work on a Đapp for this contract and need more events The project is 50% done.. Few days and I upload it.

I would like thank your reports, please give your ethereum address.

Best regards:
-IFA

Hey Ifa,

I think the chances are more fair now.
It's still only 1/26 for *10 gain but it's working as advertised.

BUT !!!!
I think there is a big problem in your code.
when a player wins you have this line to send :
      if (value_ > 0) { if (msg.sender.send(value_)) { throw; } }

this means that the transaction fails if you send the win.
did you forget ==false ?
Or is this intended

I'm puzzled ><

Thanks! Nice! I wait your response.

GJob for the update.
I will read the code when I have time and let you know what I think.

News!

Type D contract is ready to use!

This is a unique gamble game wo you can be Player and Investor in the same time!

Website:
http://d.ethereumlottery.net
(Play from the website is still under development.)

Yesterday have increased the faucet claim reward from 10-25 szabo to 10-50 szabo.
50% ref and 10 minute claim delay is still available.
http://faucet.ethereumlottery.net

This is the reason that we need to work with big numbers.

Please check this my Friend: http://pastebin.com/fhF3i6y0
If you see, when you increase the number then the result will be 0 on every 26 time. This mean: 1:26 for get the result: 0 !

I have now whats wrong! When the Difficulty changes under 1 million then the success rate is absolute high.
Example when you want play with 1.1 ether and you get 118181817 Diffi, then you have 1 : 59 090 908 rate. This means the calculation is wrong.
I disable the contract until i can fix this problem.

Very thankful for your report!

I will reply when i'm done with the contract.

Best regards:
-iFA

no it's false. You assume you can divide both sides of the modulo and preserve the chances, it does not work like that.

the bignumber*1million should be a multiple of 118'181'817 for your contract to trigger the transaction.
that's 1 chance over 118'181'817

it's not the same as bigNumber divisable by 118 which is a chance over 118.

Btw you should know that there are no float (real) numbers in solidity so your 118.18 makes no sense.

I have a lot times tested today.

If the Difficulty is 26'000'000 you have 1:26 rate for win.
When you play with 1.1 ether, then the Difficulty is 118'181'817. Thats mean you have 1:118.181817 to win.

This is simple Math

so suppose you have

bigNumber % 118 =0

you don't have big Number * 1 million % 118181817

I have edited my message,
I think it is not correct in fact !

Your welcome!

Yes correct!

So i create the contract again

Thanks for the clarification IFA,

I think it's clearer now, but I'm not sure it's solved.

So If I understand you, you say that

big Number * 1 million % 26 * 1 million

is the same as

big Number % 26 ?

I'm not sure the probabilities are preserved.
In this case yes because we can factor 1million in each side.

But take for instance a bet of 1.1 ether, difficulty of 118181817.

so now it would be
big Number * 1 million % 118181817

your proof does not work for this case, you can't divide anymore without altering the result.

Dear sydhelly,

You have confused me

I have checked the source code and i think it stills fine.
I try prove my right:

I think you have not checked this: (this is in the makeRoll function)

Thats mean when i multiple the A number what i module with the B number i got the same result.
Examples:

#1 (with lose)
bigNumber = 16171794848463
difficultyMultipler = 1000000
difficulty_ = 26000000
bigNumber * difficultyMultipler % difficulty_ = 7000000

#2 (with lose)
bigNumber = 16171794848463
difficultyMultipler = 100000
difficulty_ = 2600000
bigNumber * difficultyMultipler % difficulty_ = 700000

#3 (with lose)
bigNumber = 16171794848463
difficultyMultipler = 1
difficulty_ = 26
bigNumber * difficultyMultipler % difficulty_ = 7

#4 (with win)
bigNumber = 118268331246
difficultyMultipler = 1000000
difficulty_ = 26000000
bigNumber * difficultyMultipler % difficulty_ = 0

#5 (with win)
bigNumber = 118268331246
difficultyMultipler = 100000
difficulty_ = 2600000
bigNumber * difficultyMultipler % difficulty_ = 0

#6 (with win)
bigNumber = 118268331246
difficultyMultipler = 1
difficulty_ = 26
bigNumber * difficultyMultipler % difficulty_ = 0

I wait for you respone. I dont create new contract until we dont have cleared the situation.

Best regards:
-iFA

The solidity code is all I trust, it never lies.
And in the code, it is not divided by 1million.

Ok good to know,

Thanks a lot for the feedback Ifa

Dear sydhelly,

Thank you for your respond.

I have disabled the contract until i check this!
I don't want to create a scam contract.

Best regards:
-iFA

"a multiple of 260000000" / 1 000 000 - this step is missing in your calculation


But contact the developer - he told me this.

Dear densuj,

I dont have FAQ yet, but i would write one
The website is created for desktop use at most.

Best regards:
-iFA

No I did not make a mistake.

Check in mist :
enter 5e18 in bet
you get 26000000

And it's not a rate.
It's the value of diffculty in the equation.

bigNumber * difficultyMultipler % difficulty_ == 0


So the hash number * 1000 (diff multipler) has to be a multiple of 260000000 for you to win.
1 chance over 260 000.

I know solidity. I did not make a mistake.

This game is a scam.

No, you calculaded badly. Chance 1/26 - not 1/26000000.

Hey there.

I think there is a problem with loterry D.
I like the concept but I check my chance of winning and it's ridicilously low !!!!

If I place a 5 ETH bet, I can win *10 but only have a chance of winning of 1/26000000 !!!!!
ONE OVER 26 MILLIONS ??
that's crazy, no one in his right mind will play this game !!

We win if :
bigNumber * difficultyMultipler % difficulty_ == 0

but with the max bet of 5 ETH, difficulty is equal to 26 000 000.
So 1 chance / 26000000 that the remainder of the division will be 0.
Insanely low for a *10 gain !!!

Scam ?  

I have opened your website via android everything is ok, but there are not FAQ on there and it is make me confuse. I hope you can add it or you add something are like tutorial on the website or in here. Thanks

Yes! Finally a good work, good site! I will take into some ETH!

Thank you very much!

In the time of Bitcoin was everything script based and still use hundreds of people

Very well, good luck in your operation. I wish you the best, nice website btw. I was just shocked that people sent money to a human address.
Good LOTTERY TO EVERYONE 

Dear askolein,

Sorry for late (next day) answer.
The A and B type lottery is script based and not contract. I'm working on it to deploy as contract.
The C type is verified here: https://live.ether.camp/account/a643A6cfc95fb163DC8e94Af0D9eeDb8A6E89892
etherchain.org has some bug and i can't upload the source code of the contract. I have reported that on reddit few weeks ago, but no response. You can try too:
Contract address: 0xa643a6cfc95fb163dc8e94af0d9eedb8a6e89892
source code: http://ethereumlottery.net/source/cethereumlotterynet.sol

This is my site, i still have few player for my games. I want a fair game for everyone, if you read above/below, then you can see that when somebody had a problem then i fix it.

I know that its hard to trust in me but i do everything what i can to prove that. (Proof for every draw, creating contracts, support email/channel)

If you have any question let me know!

Best regards:
-iFA

I haven't looked into this, so I'll just give generic advice:

If it looks like a scam, it's more than likely a scam. Giving these fuckers the benefit of the doubt only puts people at risk. If they're innocent they should prove it with solid evidence.

Judging from your comment earlier, it looks very fishy indeed (once again, I'm basing my assumptions on your observation alone). If it's legit, my apologies, but so far everyone that came up with slightly shady stuff turned out to be guilty.

So, no replies?

Nobody saw that?

I APOLOGIZE, don't want to FUD or anything.

But why are you speaking to me like this "If your problem really exists... blablabla"
What the hell man?

The addresses given are not contract adresses, i'm not speaking about a bug in a code !
"spotted the problem", no problem, i'm just asking about something OBVIOUS.

Maybe i don't know something about Ethereum, and it is possible to do things without contracts? If this is the case, i apologize to the entire Ethereum community.
But if there is no contract, how can it be a Dapp?

Maybe it would be wise to ask them about the problem, they have just announced their email address two posts before.
If your problem really exists and maybe some other forum member have already addressed it, they can give you the proper answer and the planned solution with a possible timeframe.
If you are the first one who have spotted the problem, they will start to investigate and maybe they will say thank you to you for finding a bug.
Of course if it's a real scam, it should be announced and the users should be warned, but in that case you need to be 100% sure and have evidence about that.

In the first post OP asks you to post here any problem you have faced, but I think shouting 'scam' is not the way that OP thought about posting a bug here...

no contracts?

TYPE A
https://etherscan.io/address/0x5a93855e876baf09e21c7bedf72402a8a575019f
No code??

TYPE B

Important notification!
If you want play with Type A or Type B lottery, the transaction need to be a regular Ethereum transaction and not invoked or internal. Sadly the server Ethereum client (geth) can not handle these transactions! If you send ether from contract or from invoked transaction, then the server don't see that!

Hey!

Thank you!
You are the first Player in the Type B
I check that immediately and i found this in my script log:
[2016-03-21 05:02:52][DEBUG] : blocknum = 1188294 ; toaddr = 0x2833546f23208786fa91d877ae4d01e9852ae6fe ; fromaddr = 0x99796692db82200eb25da3440e078e1af11b0f2b ; value = 1000000000000000
The error was in my script. A little if error: Value_what_you_send > Ticket_Price
I have fixed it and added 5 ticket for you. 5, because you have nicely reported the bug and you are my first player.
Have a good luck!

Dear Bitart,

Thank you for askind and sorry for the late answer, i have lot of work in these days.
My answer its: no way. I stay be Ethereum and i dont want to work like a exchage.
When anyone want exchage BTC can use https://shapeshift.io/ or the others. Its very easy and fast.

A little develop log for the site:
I rename the current game to Type A, and create a other game with name Type B.
The Type B game its a lottery too. You need hit 6 numbers from 60. When you hit the 6/6 the jackpot prize would maybe 100 or 50 ether (i still thinking about that). Its really hard to work that up.
Sunday, alfter the draw of lots i increase the minimum players from 10 to 30.

Good lucky!

Hi IFA,
Do you plan to accept payments in BTC from those users who doesn't have etherum at the very moment or every BTC holder should exchange their BTCs first to ether? Thanks and good luck!
